Chapter two – Physiological impacts of ocean acidification on marine vertebrates

Human activities and global climate change give rise to the increasing concentration of carbon dioxide (CO2) in the atmosphere, which is subsequently absorbed by the ocean surface, leading to ocean acidification (OA). At present, the global OA driven by CO2 is becoming more and more serious, which poses a great threat to marine ecosystems. A lot of investigations have shown that OA has disrupted various trophic levels of the food chain in marine ecosystems, including marine invertebrates and vertebrates. These impacts are harmful to the health and stability of marine ecosystems. As a typical representative of marine vertebrates, marine teleosts are suffering from the environmental stresses caused by OA, but our understanding of the impacts of OA on these species is not profound. This chapter systematically summarizes the effects of OA on marine teleosts, including acid–base and ion regulation, fertilization, embryonic development, growth, metabolism, reproduction, behaviors, and many other aspects. By analyzing the relevant research progress, we expect to deeply understand the responses of marine vertebrates such as teleosts to OA and the related underlying mechanisms, which will be conducive to effectively avoiding the threat of global climate change and providing theoretical references for formulating effective coping strategies against OA.
